 More species, we need to be able to shut down animals

Do animals have special abilities? There have been many records of animal behavior anomalies before earthquakes. Now, scientists have tested the ability of animals to predict earthquakes, revealing the mystery.

On October 26, 2016, an earthquake occurred in central Italy. Martin wickelski and his colleagues arrived at the scene within 24 hours. Weikeski, an ecologist at the Max Planck Institute for animal behavior in Germany, wanted to test a mysterious ability that has existed for thousands of years - animals can predict when an earthquake will occur! A farm near the earthquake disaster area proposed the best conditions to verify the theory.

At present, they have screened data on the behavior of farm animals for several months and more than 18000 earthquakes (mostly small-scale earthquakes). Wicksky and his colleagues found that animals have a common behavior pattern. In a study published in the Journal of animal behavior, they reported that animals would have a special reaction before an earthquake.

Aftershock effect

The study was carried out shortly after the October 26, 2016 earthquake. Wicksky and his colleagues rushed to the farm in the disaster area to label farm animals, hoping to understand the animals response to the aftershock. They label the animals: six cows, five sheep, two dogs, two chickens, a turkey, and a rabbit. Fitbit sensors are attached to these animals to measure their outdoor trajectories. Two days later, when another earthquake struck, wicksky had a rare opportunity to monitor animal behavior before, at the epicenter, and after the earthquake.

After this period of monitoring, they came to the farm for the second time in January 2017 to re label the animals until April 2017, during which time chickens and turkeys were slaughtered for consumption. The researchers collected time axis data on the behavior of cattle, sheep and dogs in October 2016 and January April 2017, and compared the time axis of animal activity with that of earthquakes in the same period. They collaborated with Winfried pohlmeier, an economist at the University of Konstanz in Germany, using established econometric models to compare the two datasets.

The ability of animals to predict earthquakes

Their research results show that animals have a consistent behavior pattern before each earthquake. Of the nine earthquakes of magnitude 4 or above that occurred in January April 2017, the animals predicted eight times. However, this expected behavior only occurs when animals are locked up, but not when they freely move in open pastures. We dont know why, and at the same time, the team found that the farther away from the epicenter, the longer they changed their behavior, suggesting that the animals felt a slow spreading signal.

In addition, it is only when the collective behavior of the three species is taken into account that the unusual behavior pattern before the earthquake is very important. Changes in individual behavior are almost irrelevant. Each animal perceives its environment differently. If you integrate their sensory systems, youll get a new way of perceiving the environment. In theory, this is the sixth sense of an animal, wicksky said

Previous studies have reported anecdotes of unusual behavior of animals before the earthquake, such as toads jumping out of ponds on the eve of the 2009 LAquila earthquake in Italy, and eyewitnesses reported herds of cattle running down the mountains before the earthquake; and in 2011, witnesses used cameras to capture the unusual behavior of wildlife before the contamana earthquake in Peru For. Records of anecdotes are not conclusive evidence, there is a lot of uncertainty, wicksky said
